I thought my answer answered even your rephrased question; I’ll try again.
Random events happen in all lives. Some cannot be survived with X resources, but can be survived with Y resources. If you’re already above Y, and the cost of a lottery ticket is low enough that it won’t bring you below Y, then you’ll survive anyway, and buying a lottery ticket won’t significantly harm you. However, if you’re already below X, and a lottery win will bring some of you above Y, then buying a lottery ticket still won’t significantly harm you (as you’re going to die anyway), but that fraction of you who are boosted above Y will survive when they otherwise wouldn’t have.
Put another way: having some of me alive is better than having all of me dead.
I guess I was looking at this with the wrong frame of mind. I don’t think quantum immortality is possible, hence my question. I wasn’t even taking it into consideration. But if you believe in quantum immortality, I can see how playing the lottery might be beneficial.
I’ll rephrase my question. Why do you want to make things better for one of ‘you’ at the expense of making them worse for many of ‘you’?
